الترابط العددي في القرآن الكريم ان الاعجاز العددي لايقتصر على التساوي في تكرر الالفاظ.. اذ ان فيه التناسب في الاعداد فمثلا تكرر لفظ الرحمن في القران الكريم 57 مره.. وتكرر لفظ الرحيم 114 مره.. اي ان الرحيم تكرر ضعف الرحمن وتكرر الجزاء 117 مره.. وتكررت المغفره 234 مره.. اي ان المغفره ضعف الجزاء وتكررت الابرار ضعف ماتكررت الفجار.. فبينما ذكرت الاولى ست مرات ذكرت الثانيه ثلاث مرات وتكررت اليسر ثلاث اضعاف ماتكرر العسر.. فقد تكررت اليسر 36 مره في حين العسر 12 مره وكذلك فيه الترابط العددي فنجد ان لفظ قل.. وهو الامر من الله سبحانه وتعالى تكرر 332 مره في القران.. ومجموع الفاظ قالوا من الانس والجن في الحياة الدنيا والاخره 332 مره وايضا نجد ان الشهر قد تكرر 12 مره.. اي بقدر سنه وان اليوم قد تكرر ايضا 365 مره.. اي بقدر سنه 2Fadwa Flemban

Non Parametric Tests الاختبارات اللامعلمية عند وجود خلل في أحد الشروط الواجب توفرها لإستخدام اختبارات t نلجأ للاختبارات اللامعلمية. الاختبارات اللامعلمية المناظرة لاختبارات t تكون أقل قوة. 4Fadwa Flemban

Non Parametric Tests Fadwa Flemban5

Non Parametric Tests One-Sample The Binomial Test Example: random sample was withdrawn for a number of children's weights and were as follows: 35, 25, 15, 20, 30, 24, 35, 15, 25, 30, 32, 33, 34, 16, 19, 20, 31, 10. Required test the hypothesis average weight of the child over than 25 kilos at the confidence interval 99%? Fadwa Flemban6

Mathematically solution Fadwa Flemban7 H 0 := 25 H 1: > 25 Use a = 0.01 Compute for the z – statistic. = = 0 from observations the sign= (It means s = 8, n = 18-2 = 16 ). Compute for the critical region. At a = 0.01, we reject H 0 if z>z 0.01 (z>+2.33). Thus, we don't reject the null hypothesis and conclude that the average weight of the child equal 25 kilos.

Analyze  Nonparametric Tests  Binomial Fadwa Flemban8 Solution by SPSS

Fadwa Flemban9 The result: p-value (1-tailed) = 0.815/2= 0.41 a = >0.01 don't reject H 0 The result: p-value (1-tailed) = 0.815/2= 0.41 a = >0.01 don't reject H 0

Non Parametric Tests Two-Independent Samples The Man-Whitney test Fadwa Flemban10 Example: To compare the ratios of intelligence between the two schools A and B, selected a random sample of students from these schools, intelligence test was conducted and the results were: A B test the hypothesis that the students in the school A are smarter than the students in the school B at the level 0.05?

Fadwa Flemban11 Mathematically solution rankschoolObs. 15A A A A 21 20A A 20 4A 18 20A 24 15A 22 22A 25 20A A 20 rankschoolObs. 4B18 9.5B20 2B17 15B22 6.5B B B21 1B16 4B18 9.5B20 Rank all observations in increasing order from smallest to largest. Assign the smallest observation the rank 1. If some observations have tied values, assign the rank that is the average of the ranks they would have been assigned if there were no ties. Rank all observations in increasing order from smallest to largest. Assign the smallest observation the rank 1. If some observations have tied values, assign the rank that is the average of the ranks they would have been assigned if there were no ties.

Mathematically solution 1.H₀ : µ1=µ2,H1 : µ1>µ2 2.W=( )=171.5 Fadwa Flemban12 Compute for the critical region. At a = 0.05, we reject H 0 if z>z 0.05 (z>+1.65), from above 2.21 > 1.65 Thus, we reject the null hypothesis and conclude that the students in the school A are smarter than the students in the school B at the level 0.05

Solution by SPSS Analyze  Nonparametric Tests  2 Independent Samples Fadwa Flemban13

Output: Fadwa Flemban15 p-value: (1-tailed) = a = 0.05, 0.014<0.05 we reject H 0 Students of school A are smarter p-value: (1-tailed) = a = 0.05, 0.014<0.05 we reject H 0 Students of school A are smarter

Non Parametric Tests Two-Related Samples The Wilcoxon test Fadwa Flemban16 Example : Two people decided correct the answer sheet of 20 students in statistics, were them degrees as follows: A B Test the hypothesis that the person A gives the degrees different than the person B at the confidence interval 95%?

Mathematically solution H 0 : µ1 = µ2 H 1: µ1 > µ2 Use a = 0.05 Compute for the z – statistic. (T =( ) =112 ). Compute for the critical region. At a = 0.05, we reject H 0 if z>z 0.05 (z>+1.65). Thus, we reject the null hypothesis and conclude that the person A gives the degrees larger than the person B. Fadwa Flemban17

Fadwa Flemban20 Output: The result: p-value= <0.05 we reject H 0 the teacher A gives the degrees different than the teacher B. The result: p-value= <0.05 we reject H 0 the teacher A gives the degrees different than the teacher B.
